vscaring. (c1. 255431)' Generically this invention relates to apparatus for forming in a concrete or like masonry surface a crevice or key-way, but it is more particularly directed to such an apparatus adapted to be readilyfremoved'therefrom without damage to the; concrete and susceptible of'repeated use.

One of thev principal objects of this invention is the provision of a collapsible and separable vflashing'reglet template or mold for forming a crevice in aconcrete Wall 'or like masonry sur- .face adapted to receive an'dlockingly anchor the flashing therein, said template Ibeing readily removable for repeated use. 1

Ithas heretofore .been prevalentl to attach a flashingreglet to the face ofA a wooden or other form,- cons'tructed of .copper or the like bent to form a hollow projection having, in some instances, an uneven or saw-tooth 'formation in one wall and when the concrete forming the wall or other surface of the masonry structure has set; the .reglet remains embedded in the concrete forming a lining for the slotf or crevice formed thereby, and locking theedgesof the flashing inserted therein in place. Thus'the crevice or slot of the desired configuration is generallyV formed in the masonry wall just above the jointure of a roof portion therewith or other joint to befsealed, extending throughout the length of the wall-and, in connection with spandrel Waterproofing, extending continuously around theentire building, therefore lthe copper slot forming reglet embedded 'in the wall, as heretofore employed, must `be coextensive therewith, and in addition it'usually extends above the crevice constituting a continuation of the outer surface of thefwall which from the point of appearance is not alwaysdesirable. 1

It is obvious that the quantity4 and cost ofthe material 'thus required for each ilashingoperation, simply in thel formation ofthe .crevice or recess, is considerable, and, therefore, oneofi the principal objects of this invention'is the provision of ra separabledemountable template or'mold of.

y .simple construction, requiring a minimum ormaterial, adapted upon'setting of the concrete to be readily withdrawn laterally from the crevice: for repeated use, therebyeliminating the necessity i forand cost of the material andtime and labor required in preshapingit toy form the'crevice incident t'o each successive 'flashing' operation.

With these and 'otherA objects inview, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangementv of parts, hereinafter morev fullyJ describedand. claimed, and illustrated in the-accompanying'drawing, in'which like characters ofreference indicate like parts throughout the several figures, of which: Fig'. 1 isa fragmentary vertical sectional view through a concrete wall, wooden form and template 'structure in crevice forming position.

Fig. 2`is a view-similar to Fig. 1 withthe-wooden form-and template vor mold removed, and showing the flashing inserted in the crevicein locked position. Y I Y Figs; 3; 4, and 5 are` fragmentary perspective views of thevcomponent's of the template'in disassoeiated relation;

In the illustratedv embodiment characterizing this -invention'there is shown a Wooden form'in position to form the face or surface 6 of aV wall 'I Vof a masonry structureconstructed of concrete or cementitious aggregate 8 having formed there-V in acrevice or slot-Sf-in which is adapted to be inserted andlockingly retained in place flashing IIL fronrwhich extends-upwardly and-rearwardly abase portion I2 of a width substantially corresponding to the desired depth of the crevice'or slot key-way 9. l-Said'base portion I2 at its rear edge isbent upwardly forming the `rounded edge I3v and portion I Iv-extending upwardly at an an;

g-le from the edge -I'3-and adjacent its free edge isbent lip'IS.` The section b constructed of metal or other suitable materialiisadapted for interlocking andV detachable connection-with-section a'and comprises `portion I'Iv formedvat itsrear edgewith'a complementalunderlying lip y I8 for' interlocking detachable engagement with-lip I6 of section a, as shown in Fig.V 1. Said portion I-'I extends upwardly in slightly off-setrelatiori with respect to and constitutes-a continuation of portion I4, and isv curved downwardly as at- I9 to-a point 2liand. bent inwardly formingthe lateral flange or'v shoulder 2I extending in substantially horizontal alignment with the interlocked lip I6 and then downwardly forming the vertical flange 2'2;

Thefflanges Il and 2l` are formed with openings 23adapted to re'ceivenails'or other fastening elements" 2`4 andl 25, respectively, asv will directly more fully appear.

Thespacer'section c is constructed from Wood upon itself as hat I5 forming the overlying or other suitable material and of a size adapted to fit in between the portions 2I, 22, I2 and form 5, and is formed with parallel vertical sides '26 and 21, a horizontal top side 28, and an inresting on the upper side 28 is secured to said The lip I6 is then strip c by small nails 25. interlockingly engaged with lip I8 and portion I2 with the inclined surface 29 of section c and flange II is then secured to form by fastening facilitating its removal; and by reason of its design, separability and manner of connection with the exterior wall form, the outward movement of said form automatically effects separation of the interlcked and interconnected sections and removal of the template from said crevice, said template obviating the use of a flushing reglet or crevice forming material for each successive flashing operation, and at the same time being simple in construction, requiring only a minimum of material, manufacturable at a reasonable cost, and efficient for the purposes Y intended.

elements 24, whereupon said template Ais in operative position to form the crevice 9 when the concrete 8 has been poured around said template and as soon as said concrete has sufficiently set or'hardened the template may be readily removed. ,l

. The section b is only lightly secured to section c by the small nails 25 and the outward movement of form 5 in removing direction separates said section c from section b and at the same time effects outward movement ofsection a withdrawing lip I6 from engagement with lip I8, and section b either dropping down and removed on section la, or if section b for some reason fails to immediately drop, section a may be halted when partially withdrawn and said section b easily loosened for removal as stated.

For purposes of illustrationV the crevice 9 (Fig. 2) has been left open but `it will be understood that after the flashing has been positioned therein, ,said crevice may be filled with the material 8 orother mastic, as desired. Further, the template A may comprise a single length or a plurality of sections arranged in end to end relation depending upon the length of the desired crevice. A While it is Atobe understood thatI do not desire to conne myself.v to the exact shape of the crevice or recess 9, it will be noted that the instant design, including the inclined wall 3l, the shoulder 32 and receding end wall 33, lends itself to the easy insertiontherein of the counter flashing Ill, which is bent backwardly at a point spaced from one edge in a direction upon itself forming the portion 34 extending upwardly at an angle with respect to the inclined portion 35,;so that said flashing Ill may be slidably inserted along the inclined wallY 3| and When it has reached its anchoring position the free edge of the portion 34 will spring behind and in anchoring and locking engagement with shoulder 32 and thereby firmly securing said flashing in operative position. Should replacement of flashing I0 become necessary, the space provided by the end Wall 33 permits sufficient adjustment of the flashing to break the binding engagement of portion 34 with shoulder 32 to enable depression thereof and removal of the flashing from the crevice.

It will be apparent that I have provided a reglet template adapted to `form in av masonry structure a flashing anchoring crevice of a design enabling the ready insertion of the flashing therein and, if desired, its removal therefrom, said template including interlocking separable sections having rounded edges to obviate any wedging effect with the set concrete, the outer surface of the template being preferably treated withV a suitable lubricant to insure its non-sticking with the crevice walls and, thereby, further 'Although in practice it has been found that the form ofthe invention illustrated in the accompanying drawing and referred to in the above description as the preferred embodiment is the most eilicient and practical, yet realizing that conditions concurrent with the adoption of the invention will necessarily vary, it is well to emphasize that various minor changes in details of construction, proportion and arrangement of parts, may be resorted to within the scope of the appended claims without departing from or sacrificing any of the principles of the invention.
